Be it known that I, LLOYD F. Nnnsoma J band to encircle the arm and support the sleeve in adjusted position.

The prime object of my invention is to provide a sleeve band in which clamp a-ws are incorporated, adapted to positively grip the material of the sleeve in addition to the holding action due to the resiliency of the band'as a whole.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a plan view embodying my invention;

Fig. 2 is a partly sectional side elevation as indicated by the line .2-2, Fig. 1;

Fig. 3 is a fragmentary side elevation showing the jaws open;

Fig. t is a fragmentary edge or top view showing in position on the band. a bow covering for the most part the clamp jaws and their springs;

Fig. 5 is a fragmentary view of the inner side of the band at the meeting ends. of the jaws.

Tn carrying out my invention in practice in accordance with the illustrated example, a strip 10 of flexible material, preferably elastic webbing, is made to constitute the major portion of the band and interposed in the band between the ends of the strip 10 are clamp jaws 11 disposed end to end and pivotally connected, there being a pivot pin 13 extending through side flanges 12 on the respective jaws. A spring 1% is coiled about the pivot pin l3 and the ends 15 of the spring are oppositely disposed to bear on the respective jaws 11 ina manner tending to close said jaws. The jaws at the opposed edges of the flanges 12 have mating teeth 16 to give a better gripping action and also preferably the teeth are formed in the tranverse edges of the j aWs 11 as indicated of an arm band i Specification of Letters Patent.

at 17, Fig. 5. The jaws are formed of suitable sheet metal and in practice the jaws at and adjacent to their toothed edges are covered with suitable soft material as indicated at 18, Fig. 5; said material may consist of flock secured by a suitable adhesive substance, or may consist of rubber leather, or other soft material applied in a manner to mmlmize the possibility of the teeth cutting the sleeve.

Preferably the strip 10 is permanently connected at one end to the adjacent end of one jaw 11, while the strip at its opposite end is detachably engageable with the other aw so that the band may be passed about the arm and the detachable ends then connected. In the form shown wire fasteners 19 are indicated permanently securing one end of the strip 10 to the jaws 11 and at the opposite sides a yoke 20 is carried by said strip and adapted to be passed over a hooked pin 21 on the adjacent jaw 11. The jaws 11, it will be observed, are sector-shaped to pre sent surfaces attheinterior of the band curving lengthwise of the jaws to conform approximately to the arm of the wearer and to complete the approximately circular form of the band.

In practice also a bow is preferably em,- ployed of a size and form to cover more or less of the metal parts that may be desired. in Figs. 1, 2 and 3 the bow is omitted in the interest of clearness. A bow 22 of one form is shown in Fig. 4, the knot of the bow being disposed over the spring and pivot of the jaws, while the ends are extended laterally over the ends of the jaws toward the ends of the latter.

It will be clear from. the foregoing that with the band in position on the arm, the jaws are adapted to break joint radially inward to be opened to grip the material of the sleeve and thereby give a positive holding action in addition to the constrictive action of the band. as a whole. It will be clear also that the elasticity of the strip 10 contributes to the holding of the jaws together in addition to the holding action of the spring.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, 1 donot limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without depari ,Gopies'of this patent may be obtained for ture from the spirit of the invention as definedin the appended claims,

Having thus described my invention, I clann as new, and desire to secure by Letters Patent:

1. A sleeve supporting band including aws placed end to end and plvotally' conneeted a strip of elastic material connected at its ends with the respective jaws, teeth on the opposed edges of the jaws, and a spring tending to maintain the jaws closed, and yieldable to open the jaws.

2. Asleeve supporting band including a flexible strip and a clamp between the ends of the strip, said clamp being curved lengthfive cents each, by addressing the Commissioner of Patents,
